Abstract (en)
[origin: WO2022216217A1] A system and a method for breath analysis. The system comprising a breath sampling apparatus configured for collecting a sample of substances from the exhalation breath of a test subject; and a sample preparation apparatus configured for extracting selected analytes from a collected sample of substances. The method of breath analysis comprising: placing a sampling disc in the proximity of xhalation openings of a test person; receiving exhalation breath on the sampling disc for a predetermined period of for example about 1 hour; collecting a sample of substances from the exhalation breath by adsorption on the sampling disc, wherein the adsorbed amount and composition of substances corresponds to the average amount and composition of substances exhaled during a length of time; placing the sampling disc with the collected substances in a desorption vessel; releasing the collected substances from the sampling disc in the desorption vessel by heating in an inert atmosphere; preparing the sample by adsorption of selected analytes among the sample of substances; analyzing said selected analytes by means of gas chromatography.
